Honored ContributorAccessing specific memory in DMA
I am trying to interface fpga and yocto in DE2i-150 board using device driver. From software side I am using DMA for memory allocation. I have 3 input data. Two of them are 416 bit long and one is 32...

Honored Contributor --- Quote Start --- How can I access this specific memory for this data in verilog file where I have a read input of 32 bits? --- Quote End --- Your question is not clear. If you are implementing a 32-bit bus master, then you just need to read your (416 bit) data using several 32-bit transactions. Maybe post your existing project and/or a diagram of what you are trying to do? You may want to consider not storing your data in memory, and instead just DMA it into registers in your component (sometimes, implementing a slave is more straightforward than implementing a master).
